Passable pipe bag hydraulic reclamation cofferdam construction method
The invention provides a passable pipe bag hydraulic reclamation cofferdam construction method, which belongs to the technical field of cofferdam construction, and comprises the following steps: step 1, cleaning an original river channel cofferdam construction range and laying geogrids; secondly, through bag hydraulic reclamation laying and upstream face protection foot hydraulic reclamation laying are conducted on the bottom of the cofferdam, and a foundation structure of the cofferdam is formed; thirdly, blow-filling laying of pipe bags on the two sides and blow-filling of sand in the center are conducted below the steel sheet pile construction platform, and a cofferdam lower layer structure is formed; and fourthly, slope protection pipe bag blowing and filling are conducted on the backwater side, and a center anti-seepage steel sheet pile is arranged in a driving mode. The problems of stability, anti-seepage performance and traffic capacity of existing cofferdam construction are solved, and the method has the advantages of being simple, easy to implement, high in operability, efficient and reliable and can be widely applied to cofferdam field construction.
本发明提供一种可通行的管袋吹填围堰施工方法，属于围堰施工技术领域，包括步骤一，对原有河道围堰施工范围进行清理和铺设土工格栅；步骤二，对围堰底部进行通袋吹填铺设和迎水面护脚吹填铺设，形成围堰的基础结构；步骤三，在钢板桩施工平台以下进行两侧管袋吹填铺设和中心砂土吹填，形成围堰下层结构；步骤四，对背水侧进行护坡管袋吹填和打设中心防渗钢板桩。以解决现有围堰施工的稳定性、防渗性能和通行能力问题，本方法具有简单易行、可操作性强、高效可靠的特点，可广泛应用于围堰领域施工中。
